A couple of weeks ago Alan and I attended a Stake demonstration of different ways to cook without power in case of an emergency. I had seen apple box ovens before, but had never used one. We were able to make one that day and I decided to use it to cook our dinner tonight. It is simple. First, you heat up about 10-15 briquettes.
While the briquettes are heating up, you prepare the food you will be cooking (or it could be prepared prior to this). I decided to try foil dinners. I used ground turkey for the patties and cut up potatoes and added carrots. I always like to top it off with a little Cream of Mushroom soup for flavor and moistness. I didn't have any onion, or I would have added that to my meal (not Alan's).
Fold the foil around the food. You will need to do this twice to prevent leakage.
This is what the inside of the oven looks like. You use four soda cans to hold the cookie sheet that the foil dinners are resting on and then put the hot charcoals under the pan.
Then you place the box oven over the meal and use one charcoal briquette to keep the box from laying flat on the ground to allow air to circulate.
My oven got a little hot. You can see it got up to 450 degrees.
After about 1 hr. of cooking time, the meal was ready to be served.
